Halifax Regional Water Commission – International Wastewater Lift Station
Project Description
Romtec Utilities designed and supplied a wastewater lift station to replace two dilapidated systems in Bedford, Nova Scotia in Canada. The new lift station uses 7.2hp Flygt pumps installed in a duplex configuration to meet the applications flow requirement. Discharge valves were installed in a dedicated vault structure adjacent to the wet well. High groundwater from the nearby body of water required a sump pump to be installed in the valve vault and discharge infiltrating water into the wet well. Level sensing is achieved using an ultrasonic transducer with multiple mechanical floats for redundancy. Water levels are detected and communicated using an ultrasonic transducer with mechanical floats for redundancy. Electrical controls for the lift station use a MicroLogix 1400 PLC and are installed in a NEMA 4X stainless steel enclosure for protection.

Why They Chose Romtec Utilities
Romtec Utilities was contacted to replace two aging wastewater lift stations with a modern system capable of handling their combined flow in Bedford Nova Scotia in Canada. This was an international project that required Romtec Utilities to meet several conditions to design the system and deliver it. We worked with the Halifax Regional Water Commission, the local water authority, and their site engineer, Design Point, to design the system for this location. All documentation was prepared according to HRWC’s standards with all units in metric. Romtec Utilities also coordinated the international delivery of components. Dexter Construction was the general contractor on this project and handled the installation of the pump station. Romtec Utilities sent an installation advisor to the job site to answer any questions about the package pump stations during the install. Once all site-work was completed and the lift station was ready to be commissioned, Romtec Utilities sent a start-up technician to provide start-up, testing, and training services for the Halifax Regional Water Commission.
